A man could arrive on time for an appointment if he drove a car 40mph; however, since he left the house 15 minutes late, he drove the car 50 mph and arrive 3 min early how far from his house was his appointment
Answer:
60 miles
Step-by-step explanation:
Let us assume the distance between his home and place of appointment be x and t would be time taken at 40 mph
As we know that
Distance = speed × time
So,
x = 40t ............(1)
As he left the house 15 minutes late and also drove his car at 50 mph and arrive 3 minutes early
So,
15 minutes = 15 ÷ 60 = 0.25 hour
3 minutes = 3 ÷ 60 = 0.05 hour
Now the actual time taken is
= t - 0.25 - 0.05
= t - 0.30
x = 50(t - 0.30)
x = 50t - 15.............(2)
Now
40t = 50t - 15
10t = 26
t = 3 ÷ 2 hour
Now
x = 40 × 3 ÷ 2
= 60 miles
Which expressions are equivalent to the perimeter of the shape? How do you know?
a. x + 3 + 3x + 1
b. 2x + 4 + x
c. 4x + 4
d. 2x + 2 + 2x + 2
The expressions are equivalent to the perimeter of the shape is c. 4x + 4
What is perimeter?The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.
Perimeter of the rectangle = 2(length+width)
Given the paramters are;
length = x + 1
W = x + 1
Perimeter of the shape= x+1+1+x+x+1+x+1
Perimeter = x+1+1+x+x+1+x+1
= 4x + 4
This is the expression equivalent to the perimeter of the shape
The answer is c.

You have 2 different savings accounts. For Account A, the simple interest earned after
6 months is $4.63. For Account B, the simple interest earned after 21 months is $16.80. If the interest rate is 3.7% for Account A and 2.4% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or initial amount of money invested.
R represents interest rate
T represents time
Considering the investment on account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years
6.94 = (P × 3.7 × 0.75)/100 = 0.02775P
P = 6.94/0.02775 = $250
Considering the investment on account B,
I = $13.80
R = 2.3%
T = 18 months = 18/12 = 1.5 years
13.8 = (P × 2.3 × 1.5)/100 = 0.0345P
P = 13.8/0.0345 = $400
To determine the account that earned more interest in the first month,
250/9 = $27.8
400/18 = $22.2
Account A earned you the most interest the first month because $27.8 is higher than $22.2
A pair of shoes that originally sold at $30 is now being offered at a 25% discount.
What is its present price?
Answer:
$22.5
Step-by-step explanation:
You will pay $22.5 for a item with original price of $30 when discounted 25%.
Answer:
Refer to explanation
Step-by-step explanation:
The screenshot you put is the correct answer, here's another method to get the same answer:
Find what 25% is.
100% = 30
1% = 30 ÷ 100 = 0.30
25% = 0.30 x 25 = 7.50
Find the price after the 25% discount.
100 - 25 = 75
75% = 30 - 7.50 = 22.50 or 0.30 x 75 = 22.50 (Both solutions give the same answer)

Imagine you measure the length of 15 cars, and then sum that length, in order to see how big a parking lot must be. You do this in two different ways. First, you use the same bad tape measure for each car so that your measurement is always 1 cm too long, or always too short, for all of the measurements. For your second attempt, you use a different bad tape measure for each car, so there is an uncertainty of plus or minus 1cm in each measurement. What is your estimate of the total error in the sum of all the car lengths in these two cases
Answer:
± 15 cm
Step-by-step explanation:
In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.
In the second case, the uncertainty or error is also ± 1 cm.
Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm
So, the total error in both cases is ± 15 cm.

Tyler has $125.00 to spend on books and CDs. He buys one book for $30.00. He wants to spend the rest on CDs that are on sale for $9.00 each. Which of these statements is true?
a.He can't buy any CDs.
b.He can buy 11 CDs.
c.He can buy more than 11 CDs.
d.He can buy 10 CDs.
Answer:
d. He can buy 10 CDs
Step-by-step explanation:
The reason he can only buy 10 is because if the CDs are $9.00 each then you would multiply:
10 x 9 = $90.00
If you add the $30.00 of books:
$90.00 + $30.00 = $120.00
This means he does not have enough money to buy another CD. He has $5.00 left over.

5. Solve the equation - 4(x - 1) + 6x = 2(17 -- x) for x.
Answer:
x = 15/2 or 7.5
Step-by-step explanation:
-4 (x - 1) + 6x = 2(17 - x)
First, distribute the -4 and 2, and remember that multiplying two negatives make a positive.
-4x + 4 + 6x = 34 - 2x
Combine like terms
2x + 4 = 34 - 2x
Subtract 4 from both sides
2x = 30 - 2x
Add 2x to both sides
4x = 30
Finally, divide both sides by 4
x = 15/2 or 7.5

For this exponential function what is the output value (y) when the input value (x) is 3?
The value of the function y = 5(2)^(x) at x = 3 is (3, 40).
What is an exponential function?An exponential function is in which the power to a constant value is independent.
Given, y = 5(2)^(x).
Now at x = 3 we'll replace the value of x with 3, therefore
y₃ = 5(2)^(3).
y₃ = 5×8.
y₃ = 40.

Michael has a points card for a movie theater. He receives 70 rewards points just for signing up. He earns 8.5 points for each visit to the movie theater. He needs at least 165 points for a free movie ticket. What is the least number of visits he needs to make in order to earn a free movie ticket?
Answer
The true least number of visits is the lowest whole number above 11.176470..., which is 12.
Step-by-step explanation:
points per visit, # of visits + sign-up points ≥ free tickets points
8.5 (points per visit)
70 (# of visits)
165 (free ticket points)
8.5v ≥ 70 + 165
70 + 8.5v ≥ 165
8.5v ≥ 165 -70
8.5v/8.5v ≥ 95/8.5
